Introduction
Generates a plot file containing a plot title.
How to use
The title block is placed centrally above the data area. Up to 80 plottable characters may be entered; the actual number depends on the width of the data area and the character size chosen. The characters are placed centrally in the title box, which also includes a Datamine title at the left of the box, and above the user-supplied title.
Title plot files may be APPENDed to any other files. Because no data input file is required, it is usual to use the plot file written out by a previous plot process as the prototype for the PLOTTI process. This removes the need to specify scaling parameters. However, if a null plot prototype is used (without scaling information in it) the parameters may be supplied in the normal way.

Error and Warning Messages
|
Message |
Description |
Solution |
|
>>> CANNOT APPEND TO NON-EXISTENT OUTPUT FILE. >>> A NEW OUTPUT FILE WILL BE CREATED |
The @APPEND parameter has been set to 1, but the specified plot file does not exist. A new file will be created to contain the new plot being produced.
|
|
|
|
|
|
|
>>> ERROR - CANNOT APPEND TO PLOT FILE AS IT DOES >>> NOT CONTAIN ALL THE REQUIRED FIELDS. >>> THE PLOT FILE WILL BE OVERWRITTEN. |
The @APPEND parameter has been set to 1, the specified plot file exists but is invalid. The existing plot file will be overwritten by the new plot being produced.
|
|
|
|
|
|
|
>>> FATAL ERROR, BAD SCALE/RANGE COMBINATION(S) <<< >>> XMIN, XMAX = nnnnnnnnnn.nn nnnnnnnnn.nn >>> YMIN, YMAX = nnnnnnnnnn.nn nnnnnnnnn.nn >>> XSCALE, YSCALE = nnnnnnnnnn.nn nnnnnnnnn.nn |
Either insufficient scale information had been entered (at least two of XMIN, XMAX, XSCALE or Y equivalents must be entered either from the prototype of from parameters) or the combination given of XMIN, XMAX, and XSCALE (or their Y equivalents) was impossible. Often caused by entering a null plot prototype and no parameters. Fatal; the process is exited.
